Spoofing is a cyberattack technique where a malicious actor disguises themselves as a trusted source to deceive systems or users. In cybersecurity, spoofing can involve faking email addresses, websites, or network addresses to trick people into revealing sensitive information or granting unauthorized access. In the context of GPS, spoofing refers to sending fake GPS signals to receivers, causing them to display incorrect locations. This can disrupt navigation, logistics, and security systems that rely on accurate positioning. Spoofing attacks exploit trust and can lead to data breaches, financial loss, or operational disruption.
